This invention relates to the binding of booklets, catalogues and otherpublications on wire stitching machines and is more particularlyconcerned with saddle stitched booklets and the like.

In wire stitcher-feeding machines for inserting and stitchingsaddle-stitched work, sections of folded paper, hereinafter referred toas signatures, are placed on the stitching machine at a number offeeding stations, each of which is provided with a saddle bar forreceiving the signatures, and a conveyor chain gathers the signaturestogether from each station and feeds the gathered signatures, with theircovers, to a stitcher head where wire stitches are inserted through thebacks of the booklets or the like thus formed.

Booklets and the like bound and s titched in this way have thedisadvantage that the covers are liable to be torn off, since they areonly secured by the wire stitching. 'One of the objects of the presentinvention is to overcome this disadvantage by applying a hot or cold athe back and/or sides of one or more dhesive to of the insertedsignatures, and essentially the outer signature, when travelling orstationary on the-wire stitching machine and prior to the cover beinglaid on the gathered signatures, whereby the cover is adhesively securedautomatically to the back of the outer signature in addition to beingstitched thereto with wire stitches.

Although the primary object of the invention is to secure the cover tothe outer section of the booklet more, securely than hitherto,

it will be clearly understood that each or any of the insertedsignatures may be adhesively secured to one another in the same waybefore the wire stitching operation is effected.

In order that the inventiorrmay be better understood one particularembodiment thereof will now be. described with reference to theaccompanying drawing, but it must be understood that the constructionand arrangement of the embodiment illustrated may be many respectswithout departing from and scope of the invention.

In the drawing Figure 1 is a side parts, in varied in the spiritelevation showing the conveyor, feeding stations and a stitcher head ofa wire stitching machine provided with adhesive applying means according to the invention; and Figure 2 is a sectional view of a modifiedpart of the adhesive applying means.

Referring to the drawing the machine comprises a plurality of saddlebars 2 for receiving the signatures 3 which are to be collected togetherand bound into book form and a conveyor chain 4 for collecting thesignatures and conveying them to a device, indicated generally at 5, forapplying adhesive to the back and/or sides of the outer signature andfinally to head 5 where wire stitches are inserte a stitcher d throughthe backs of the booklets after the cover has been laid on. The adhesiveapplying device in its simplest form comprises a container 1 for theadhesive rigidly mounted above the conveyor chain 4 and provided with aroller'8 rotatably' :mounted in bearings in the walls of the container Iand projecting through an aperture in the bottom of the container. Theunder side of the roller 8 lies in substantially the same horizontalplane as the upper edge of the saddle bar 510 2 or slightly below thisplane so as to ensure that the back or folded edge of the signaturecontacts with the roller as it is slidden 01f the saddle bar. The roller8 may be plain or may be grooved, as shown on an enlarged scale inFigure 2, whereby the sides as well as the backs of the signature 3 arecoated with adhesive'as will be. clearly seen from the figure.

It is an essential feature of the invention that adhesive should beapplied to the back and/or sides of the outer signature, that is thesignature immediately adjacent the cover, so that an adhesive applyingdevice 5 must necessarily be located between the last pair of saddlebars-2, that is to say between the saddle bar upon-whichim; the lastsignature is laid and that upon" which the cover is laid. In certaincircumstances, however, it may be desirable for each of the insertedsignatures to be adhesively secured together and in this case anadhesive applying device 5' must 13.30 be provided between each pair ofsaddle bars.

In operation the individual signatures, which are to be bound into bookform, are placed on the saddle bars 2 from which they are removed ontothe conveyor 4 by pusher members 9 carried by 2:35 the conveyor in knownmanner. The conveyor then carries the collected groups of signaturesunder the roller 8 which applies a coating of adhesive to the backand/or sides of the outer signature, as described above, whereupon thegroupciio of signatures are carried past the last saddle'bar from whichthe cover of 'the booklet is removed by the pusher members of theconveyor onto the adhesively treated outer signature of the group. Thecomplete booklet is then carried by the 0011-3545 veyor to'suitablestitcher mechanism 6 where the booklet is stitched with wire stitches inwell known manner.
